Horse-power



` Spzicaton'forming part ofLetters To all whom z'z may concern." i j` Be it known thatI, CLEMENT RUSSELL, of Massillon, .in the countyof Stark and vState of Ohio, have invented a new and useful Improvement in Double-Geared I-Iorse- Powers; and Ido hereby declare that the following is al full, clear, and exact description of the same, reference being had to the this specication, in which- Figure l, is a vertical longitudinal section of a double geared horse powerr with my y improvement applied to it. Fig. 2, is a plan i `or top view of a portion of the same, the hub of the annular driving wheel being broken out so as to allow of my improvement being seen. `Similarletters of reference in each of the several figures indicate corresponding parts.

Before setting forth the nature of my imhorse powers, itis deemedadvisable to state that in the useof all double geared horse powers which employ an annular geared driving wheel and two transmitting pinions, much difliculty has been experienced from jone of said pinions doing all the work at `certain points while the other remains passive or out of connection` with the driving wheel, resulting from unequal shrinkage in i the castings or other imperfections which it t. is very diiicult toobviate in so large a machine. And in order to* overcome the se-i i rious effects resulting therefrom the axis of i u fthe annular internal geared driving wheel l has been made capable ofadjusting itself or moving laterally'to theright or left so that the teeth of said wheel might always be made to gear withxboth `of the pinions `at `thesame time. This arrangement which howeverbeen abandoned as useless, on "account of the difficulty found in keeping `the `axis confined and-steady, no provision being made for so doing other than providing the axis with; a head anddpassing it `down through the slot in whichfit played, and securing it by a nut, which `arrangementallowed of its soon working.-` loose, rendering the operation of the machine very unsteady z and irunperfect.` f

` My improvement is designed to prevent u all possibility of the pin working loose and `becoming unsteady.

. `The nature of said improvement consists accompanying drawings, forming part of` provement, which refers to double geared.

.n having the axis A, of the annular `driving wheel B, lit snugly in a solid flanged self adjusting or sliding box which is made in two parts D, D, and fitted in an oblong slot E, formed in the bridge F, and allowed to slide freely back and forth'in said slot as the irregularparts of the annular driving wheel B, come opposite or in contact with `the transmitting pinions G, Gr, and at the same time prevented from having any vertical movement or play up and down and also from having any lateral play other than in lines at right angles with said pinions Gr, G, by reason of being fitted snugly in the slot and the lips or flanges a, a, a, a, which are cast on the upper and lower section of the box and bearing snugly against ribs or ways b, Z), b', b', cast on the under and upper surfaces of the bridge, said flanges being caused thus to 'bear against the ribs or ways by means of a nut H, which is screwed on the screwed end of the axis or pin of the driving wheel after the box is fitted in the slot and said axis, which serves for locking the two sections together, has been passed through the central hole e, of the box. In order to insert the box in the oblong slot E, the lower section on main part D, must be separated from D, and passed up from the `under side of the bridge through the slot, until its anges or lips bear against the ways Z9', when `the upper section or cap `D must be inserted from the upper side of the bridge into the slot until its flanges or lips bear against the ribs or ways b, b, and it come in contact with the section D, when the pin or axis A, must be passed down through the central hole e, in the box until its shoulder f, bears on the cap, when the nut I-I must be screwed on the lower end of said pin or axis until all the parts are forced v`snugly together as shown inthe drawing.

By thus arranging and conning the axis it is subjected to but very'little strain and wear, and, consequently, all liability of its soon working loose and becoming unsteady and thereby causing the operation of the machine to be imperfect is overcome, and at the same time the use of a center which is capable of shifting or accommodating itself to any irregularities or imperfections in the `main driving wheel is rendered practicable,

and consequently' the disadvantages` arising from said imperfections or irregularities,

avoided.

I do not claim having the axis of the main enges a, a, a, a, in an oblong slot E formed driving Wheel of double geared horse poW- in a bridge F, as constructed, and arranged 10 ersvlnhovaxle as this is common, but, in the manner and for the purpose set forth.

at do claim is, 5 Providing a broad solid ianged boxer CLEMENT RUSSELL' center C, for the axis A, to rest in, When 1Vitnesses: said box is made in two parts D, D', and W. F. RUDENSTEIN, fitted and conned by the axis itself, and J'. KEEL.
